Abstract

The invention relates to the field of sensors, and discloses a pressure sensor self-correction method, equipment, a storage medium and a device, and the method comprises the steps: obtaining a workingtemperature set of a pressure sensor through a temperature obtaining module in the pressure sensor under the condition that the pressure is constant; obtaining a display pressure value set of a pressure sensor corresponding to the working temperature set; determining a pressure change coefficient of the display pressure value along with the temperature change according to the temperature set andthe display pressure value set; acquiring current temperature information of the working environment of the pressure sensor; and calibrating the pressure sensor according to the current temperature information and the pressure change coefficient. The pressure change coefficient of the display pressure value changing along with the temperature is determined by acquiring the working temperature setand the display pressure value set of the pressure sensor, and then self-correction of the pressure sensor is achieved through the current temperature information and the pressure change coefficient.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a pressure sensor self-calibration method, equipment, storage medium and device. Background technique [0002] The pressure sensor is an instrument that converts pressure signals into electrical signals. Due to its advantages of good stability, high reliability, and strong environmental adaptability, it has been widely used in various links of industrial production. Regular measurement and calibration of pressure sensors It is a necessary work to ensure the accuracy and reliability of the pressure sensor measurement data. [0003] In actual use, pressure sensors are susceptible to environmental information, especially temperature factors. Pressure sensors are difficult to calibrate pressure sensors in special scenarios. For example, it is difficult to calibrate water pressure sensors when measuring dam water pressure; steam The temperature inside the chamber is too high to calib...
